Proactive Health Checks
It helps you sleep better at night knowing that the database is healthy and has no bad blocks. But how can you ensure that? Bad blocks show themselves only when they are accessed so you want to identify them early and hopefully repair them using simple commands before the users get an error.
What happes at health checks
■ DB Structure Integrity Check—This check verifies the integrity of database files and reports failures if these files are inaccessible, corrupt or inconsistent. If thedatabase is in mount or open mode, this check examines the log files and data fileslisted in the control file. If the database is in NOMOUNT mode, only the control file ischecked.
■ Data Block Integrity Check—This check detects disk image block corruptions such as checksum failures, head/tail mismatch, and logical inconsistencies within the block. Most corruptions can be repaired using Block Media Recovery. Corrupted block information is also captured in the V$DATABASE_BLOCK_CORRUPTION view. This check does not detect inter-block or inter-segment corruption.
■ Redo Integrity Check—This check scans the contents of the redo log for accessibility and corruption, as well as the archive logs, if available. The Redo Integrity Check reports failures such as archive log or redo corruption.
■ Undo Segment Integrity Check—This check finds logical undo corruptions. After locating an undo corruption, this check uses PMON and SMON to try to recover the corrupted transaction. If this recovery fails, then Health Monitor stores information about the corruption in V$CORRUPT_XID_LIST. Most undo corruptions can be resolved by forcing a commit.
■ Transaction Integrity Check—This check is identical to the Undo Segment Integrity Check except that it checks only one specific transaction.
■ Dictionary Integrity Check—This check examines the integrity of core dictionary objects, such as tab$ and col$. It performs the following operations:
– Verifies the contents of dictionary entries for each dictionary object.
– Performs a cross-row level check, which verifies that logical constraints on rows in the dictionary are enforced.
– Performs an object relationship check, which verifies that parent-child relationships between dictionary objects are enforced.
The Dictionary Integrity Check operates on the following dictionary objects:
tab$, clu$, fet$, uet$, seg$, undo$, ts$, file$, obj$, ind$, icol$, col$, user$, con$, cdef$, ccol$, bootstrap$, objauth$, ugroup$, tsq$, syn$, view$, typed_view$, superobj$, seq$, lob$, coltype$, subcoltype$, ntab$, refcon$, opqtype$, dependency$, access$, viewcon$, icoldep$, dual$, sysauth$, objpriv$, defrole$, and ecol$.

TYPE DESCRIPTION
------------- -----------------------------------------
FAILURE Block 64349 in datafile 1: '/u01/app/orac
le/dbs/t_db1.f' is media corrupt
FAILURE Block 64351 in datafile 1: '/u01/app/orac
le/dbs/t_db1.f' is media corrupt
The tool dbverify can do the job but it might be a little inconvenient to use because it requires writing a script file contaning all datafiles and a lot of parameters. The output also needs scanning and interpretation. In Oracle Database 11g, a new command in RMAN, VALIDATE DATABASE, makes this operation trivial by checking database blocks for physical corruption. If corruption is detected, it logs into the Automatic Diagnostic Repository.
DBA Consulting can do the job for you.
